Your Pontiac Bonneville is aptly named with its sleek exterior, stylish interior and powerful engine that was built to last. Make sure your car keeps going the distance by replacing a defective idle air control valve with a new Bonneville IAC valve from AutoZone.

If your Bonneville has a low RPM and irregular deceleration, you know there's a problem with the idle.
